If 10 skeins makes 4 scarves than if you multiply the skeins by 2 (20 skeins) it would make 8 scarves. There for dividing the skeins by 2 (5 skeins) it would make 2 scarves. So adding 20 skeins and 5 skeins you would get 10 scarves total
The first five terms of the sequence are {0, -1.4, -2.8, -4.2, -5.6}
<h3>Recursive function</h3>
Given the nth term of a recursive expression shown below
an =an-1 - 1.4
where
an-1 is the preceding term
a1 is the first term
an is the nth term
an-1 is
Given the following
a1 = 0
For the second term a2
a2 = 0 - 1.4
a2 = -1.4
For the third term a3
a3 = -1.4 - 1.4
a3 = -2.8
For the fourth term a4
a4 = -2.8 - 1.4
a4 = -4.2
For the fifth term a2
a5 = -4.2 - 1.4
a5 = -5.6
Hence the first five terms of the sequence are {0, -1.4, -2.8, -4.2, -5.6}

Answer:48
Step-by-step explanation:
The 6 angles with vertex P are:
- Angle APB
- Angle APC
- Angle APD
- Angle BPC
- Angle BPD
- Angle CPD
The letter P must be in the middle since this location is the vertex. Something like angle BPA is the same as angle APB. We can swap the order of the outer letters without any change to the angle itself. Effectively, this means each angle has two possible names.
For
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
the discriminant is
![b^2-4ac](https://tex.z-dn.net/?f=b%5E2-4ac)
there are 3 basic cases of what happens for different discriminants
1. if the discriminant is less than 0, then there are no real zeroes
2. if the discriminant is 0, then it has 1 zero
3. if the discriminant is greater than 0, it has 2 zeroes
so given
![0=3x^2-7x+4](https://tex.z-dn.net/?f=0%3D3x%5E2-7x%2B4)
a=3,b=-7,c=4
thus the discriminant is
![(-7)^2-4(3)(4)=49-48=1](https://tex.z-dn.net/?f=%28-7%29%5E2-4%283%29%284%29%3D49-48%3D1)
the discriminant is 1. 1 is positive, thus the equation has 2 zeroes because the discriminant is greater than 0
the answer is the equation has two zeroes because the discriminant is greater than 0
